when the bike is cool or cold it will start up fine.. after it starts up and runs for a couple minutes it wont start back up when it gets warm. Just put a new piston and rings in so dont knwo whats going on.. running full sunoco 110 .. could it be that?>
need some opinions.

Have your TPS checked... that's been the culprit many times, had the same problem, got the tps adjusted and works like a charm.
